V — OPERATION

When output voltage is available, the green LED is on.
The Output Voltage Adjust trimmer (see Figure 2) allows
adjustment of the output voltage within the range specified
in Table 1.

REMOTE VOLTAGE PROGRAMMING: In addition

to the integral trimmer, output voltage can also be
adjusted via an external variable resistance (see Figure

3B). The variable resistance specified in Table 1 must be
substituted for the shorting link between + and +S termi-
nals. Note that load effect for RKW 50W is increased
using this technique, and may exceed values listed above
under STABILIZATION.

SERIES OPERATION: When a number of power sup-

plies are operating in series, the current rating is to be lim-
ited to the rating of the power supply with the lowest
rating. A diode (Vr>2 Vo, If>2Io, Vf<< low) must be con-
nected to the power supply output terminals to protect the
unit from reverse voltage.

PARALLEL OPERATION: Identical units may be oper-

ated in parallel for increased current capability. Use either
local or remote sensing for all supplies in the parallel
group.
